The 26mm is very straight for the 3.6R. With only two small humps equally spaced for the exhaust. Take a look under your car and see how straight your bar is. If its got a lot of bends in it then your out of luck.

I am not looking to install the 3.6R 26mm bar in my LGT - that clearly wouldn't work - I am looking to install the 26mm bar from the 2013 2.5i. (the fitment concern is based on the departure from the EJ engine - I didn't know if there were any extra bends, etc. to clear the new engine design) - the part numbers in my original post are for the 2.5i bar.
